Yes, but it won't take too long: All you need to do is get to tier 2 and tier 3. Those unlock the levels 2 and 3 of each ability. It's even possible to unlock those in 2 games, a 30-min one (unlocking t2) and a 60-min one (unlocking t3).

ok, I am still in trouble I guess. Shouldn´t at least the Tier 1 Abilities (like Hunt1 and Fruit1 for Forest) stay when I am Level 1?? I allways have to start from scratch. Only Leaf and Growth stay unlocked from game to game.

Reus is kind of like a rogue-like/highscore building game, where the goal is to get as far as possible (and unlock as many resources as possible). The starting configuration is always the same, but you get better and unlock new possibilities as you go. In the first game you might need 15-20 minutes to unlock new aspects, but later on you'll be able to do it in less than 5 minutes.

You can, if you want, turn on features in advanced mode, like randomized start (start with 6 random ambassadors) or extra speed. I hope that answers your question. :)
